Introduction
This service procedure is offered as a guide to enable Bettis™ Acculine drive shaft
replacement to be performed on Bettis™ G01 - G13 G-Series Actuators.
This procedure is applicable with the understanding that all electrical power and
pneumatic pressure has been removed from the actuator.
Remove all piping and mounted accessories that will interfere with the module(s)
that are to be worked on.
This procedure should only be implemented by a technically competent technician
who should take care to observe good workmanship practices.
Numbers in parentheses, ( ) indicate the bubble number (reference number) used
on the Bettis assembly drawing and Actuator Parts List.
This procedure is written using the stop screw side of the housing (1 - 10) as a
reference and this side will be considered the front side of the actuator.
The housing cover (1 - 20) will be the top of the actuator.
When removing seals from seal grooves, use a commercial seal removing tool or a
small screwdriver with sharp corners rounded off.
Use a non-hardening thread sealant on all pipe threads.
Bettis recommends that disassembly of the actuator components should be done
in a clean area on a workbench.
